A CRANBOURNE woman was alerted to the fact that her letterbox had been set on fire by an alert on her phone.
The Cranbourne woman was out when CCTV security footage she accessed on her phone showed her Dunferline Crescent letterbox had been set alight around midnight on Sunday 19 April.
Police believe it is likely to be a targeted attack.
Police seized items than can be used to start a fire left near the crime scene and a white Holden Commodore was also seen in the area at the time.
